MACHINE'FOR T REATING HIDES OR SKINS.-

SPECIFICATION forming part of Letters Patent No. 746,144, dated December8, 1903.

Application filed September 12, 1903. Serial No. 172,857- (No model.)

To all whom it may concern;

Be it known that I, FRANKLIN J. PERKINS, a citizen of the United States,residing in Woburn, in the county of Middlesex and State ofMassachusetts, have invented an Improvement in Machines for TreatingHides or Skins, of which the following description, in connection withthe accompanying drawings, is a specification, like reference characterson the drawings representing like parts.

This invention relates to a machine for treating hides, skins, andleather, and is especially adapted, among other uses, to be employed inthe operations of putting out, unhairing, slating, &c.

The present invention has for its object to provide a simple andefiicient machine for the purpose specified and one in which the entiresurface of the skin may be treated at one operation. For this purposethe machine is provided with operatingtools, preferably rolls orcylinders provided with helically-arranged blades, vanes, or workingedges, which tools are arranged on opposite sides of the path ofmovement of a table or support, such as now commonly employed inputting-out machines, and is further provided with a carrier for thehide or skin, which is movable in a path substantially at right anglesto the path of movement of the table and which carrier serves to presenta portion of the hide or skin to the action of one of the operatingtools or rolls, so that a portion of the hide or skin intermediate itsends is worked or treated prior to the hide or skin being engaged V bythe movable table, which latter is brought into engagement with the hideor skin so that the treated portion of the hide-or skin lies over theedge of the table and requires no treatment while in this position, andthe untreated portions of the skin are presented to the action of therolls or tools lying on the opposite sides of the path of movement ofthe table, which "tools or rolls treat the portions of the hide or skinon the opposite sides of the table.

The invention is especially adapted for embodiment in machines employinga plurality of tables and. commonly known as serialtable machines, andprovision is made for moving the carrier so that a fresh skin iscession. These and other features of this invention will be pointed outin the claims at the end of this specification. p

' Figure 1 is a frontelevation, with parts broken away, of a machineembodying this invention; Fig. 2, a side elevation of themaautomatically presented to each table in sue chine shown in Fig. 1looking toward the left; Fig. 3. a vertical section of the machine shownin Fig. 1, the section being taken on the line 3 3, Fig. 1; Fig. 4, adetail in side elevation and on an enlarged scale of the carin numberand which are pivotally secured to an endless carrier, comprising linkchains 6, which are passed about suitable sprocketwheels 0 d e, mountedupon shafts fg h, supported by the uprights or side frames tj, whichlatter are erectedupon a suitable base arranged substantially in theform of a triangle, with the sprocket wheels c e in substantially thesame vertical planeand which may be considered as the front side of themachine, so that the tables or work-sup ports a are caused to moveupward in a substantially vertical path at the front of the machine.

The machine. is provided with working 1c. The sprocket-wheelso d c arepreferably tools, which are arranged on opposite sides suitable for theparticular work to be per-- formed and are herein shown as rolls orcylinders provided with helically-arranged blades, vanes, or workingedges. The working cylinders 01' rolls on each side of the path ofmovement of the table are locatedor arranged in substantially the samevertical plane, and in the present instance I have shown the machine asprovided with two rolls or cylinders m n on one side of the path ofmovement of the table and three rolls or cylinders 0 p g on the oppositeside of the path of movement of the table. Each of the rolls referredtois provided with helically-arranged blades or working edges 0.

The present invention has for its primary object to efiect a working ofthe entire surface of the hide or skin by the rolls or tools located onopposite sides of the path of movement of the table, and to this endprovision is made for causing a portion of the hide or skin intermediateits ends to be worked by one of the tools or rolls lying on one side ofthe path of movement of the table and thereafter to cause the remainingportion of the hide or skin to be worked while lying against theopposite sides of the table by the tools or rolls located on theopposite sides of the path of movement of the table. One means forefiecting this result is herein shown and will now be described. Themachine is provided with acarrier for the untreated hide or skin, whichcarrier is movable in a path substantially at right angles to the pathof movement of the table, and as herein shown comprises a substantiallyV-shaped stationary piece or member 10 and a yielding member 12, both ofwhich are secured to a supporting-frame comprising side pieces 13, whichslide upon suitable ways or tracks 14, secured to the side frames of themachine and eX- tended in a substantially horizontal direction from thefront to the rear of the machine.

The movable member 12is made sufficiently long to cause a hide or skinplaced over it to be brought into engagement with one of the rolls ortools located on one side of the path of movement of the table a, and inthe'present instance the movable member 12 presents the hide or skin tothe action of the roll or tool g, which puts out, unhairs, or otherwisetreats a portion of the hide or skin intermediate its ends. The carrieris then moved so as to shift the position of the skin with relation tothe path of movement of the table and to bring the portion of the hideor skin which has been treated by the roll q into the path of movementof a table a, which latter on its bers 10 12 of the carrier and engagesthe hide or skin, so that the portion previously treated by the roll qlies over the edge of the table. The upward movement of the table liftsthe hide or skin from its carrier and presents the untreated portions tothe action of the rolls located on opposite sides of the path ofmovement ofthe table, so that the side of the hide or skin on one sideof the table may be treated by the rolls mm and on the other side by therolls 0 19, and, if desired, also by the roll g. In this manner theentire surface of the hide or skin may be treated in one operation byworking tools which are located on opposite sides of the path ofmovement of the table. In fact, by means of this invention the rolls ortools now commonly employed in machines of this class for treating orworking only the portions of the hide or skin on opposite sides of thetable are enabled to efiect the working of the entire surface of thehide or skin. The member 12 of the carrier may be made yielding tocompensate for uneven thickness of the hide or skin, and the roll q maybe mounted in fixed hearings, or vice versa. In the present instance theroll q is shown as mounted in fixed bearings and the member 12asyielding, being acted upon by the spring 15, the tension of which maybe adjusted by the screw 16.

The rolls m n 0 19 may be yieldingly supported, which may be effected inany suitable manner, and in the present instance the rolls m 0 are shownas mounted in levers 18 19, pivoted at 20 21 to a stationary part 22 ofthe framework and having their free ends connected by the links 23 24 25toa level-2e, pivoted to the frame ofthe machine and provided with aweight 27, which may be adjustable on the lever to regulate the pressureof the rolls m 0 on the hide or skin. The rolls np are similarlysupported, being sustained by levers 31, mounted on the pivots 20 21 andhaving their free ends connected by the links 32 33 34 to the lever 35,provided with the Weight 36. The movement of the rolls or tools towardthe path of movement of the table a may be limited or arrested in anysuitable manner. The carrier for the hide or skin may be reciprocated inany suitable manner, and in the present instance I have shown one meansfor eff cting this result. For this purpose the carrier is provided witharms 38 at its opposite sides, which carry rollers 39, the latterengaging cams shown as grooves 40 in the side of disks 41, mounted on ashaft 42, which is suitably driven, and for this purpose the said shaftis provided with a gear 43, which meshes with a gear or pinion 44 on theshaft of the sprocket-Wheel d, and the said cam is suitably shaped andso timed with relation to the movement of the endless carrier for thetables as to move the reciprocating carrier for the hide or skin so asto present a hide orskin to each table in succession.

The rotatable parts of the machine are driven from a main shaft 45,provided, as shown, with fast and loose pulleys 46 4-7. The main shaftis provided with a sprocketwheel 48, which is connected by the linkchain 49 with the sprocket-wheel 50 on a shaft 51, supported at the topof the side frames t'j. The shaft 51 is provided with pinions 52, whichmesh with gears 53 on the sprocketwheel shaftf. The shaft 51 is alsoprovided with sprocket-wheels 54: 55, (see Fig. 1,) which are connectedby link chains 56 57 with sprocket-wheels 58 59 on the work rolls orcylinders op. The work-rolls m n are driven by link chains 60 61 from acounter-shaft 62, provided with a gear 63, which meshes with and isdriven bya suitable pinion (not shown) on the main shaft 45. Thework-roll q is driven by the link chain 65 from the main shaft 45.

The members 10 12 of the carrier support the sides of the hide or skinwhen the lat- IIO ter is moved upward by the table, and by reference toFig. 3 it will-readily be understood that the said members hold thesides of thehide or skin away from the tab1e, and

thereby enable the-rolls or tools to treat the portions of the hidebrought into engagement with them without danger of plaiting, cutting,or otherwise injuringthe hide or skin,

' owing to the fact that the sides of the hide or to skin, which isusually wet, are not allowed to come in contact with the table until ator about the time the hide or skin is presented to the action of theoperating-rolls. In other words, the members 10 12 serve to hold thefree ends or portions of the hide or skin away from the sides of thetable and afiord opportunity for the sides of the'hide or skin to flowor move under the action of the operatingtools in substantially the sameway as the hide or skin is now'held by operators away from the table insome forms of machines of this class;

In the operation of the machine therein shown the carrieris moved by itscams in the direction indicated by the arrow 70 a suffi cient distanceto enable the operator to readily place a hide or skin over the member12 and preferably so that substantially the central portion of the hideor skin is between the member 12 and the member 10 of the carrier, whichis then moved in the direction opposite to that indicated by the arrowby the cams, and the portion of the hide or skin resting against theinner surface of the member 12 is engaged with the operating tool orroll q, which treats or works the portion of the hide or skin betweenthe roll q and the member 12. While the roll q is working the hide orskin, as described, the circular portion of the cam-groove betweenthepoints 71 72 is in engagement with the roller 39 and the carrier isat rest. At'or about the time the roll (1 has treated or worked theportion of the hide between it and the member 12'the carrier commencesits movement toward the front of the machine and the portion of the skintreated by the roll q is moved across the path of movement of the tablea, which on its upward movement is brought into engagement with theunder surface of the hide or skin, the said table passing between themembers 1012 and engaging the hide or skin, so that the portion treatedby the roll (1 lies over or on the upper edge of the table and extendson both sides of the latter a sufficient distance to be engaged by therolls up on 0,which treat or work the portions of the hides or skins onopposite sides of the table as the latter is moved or carried betweensaid-rolls. When the table, with a hide thereon, has passed upward, soas to clear the member 12, the carrier continues its movement towardthefront of the machine and is brought into position to receive anotherhide or skin. The carrier remains at rest in what may be termed itsreceiving position by the circular portion of the cam-groove between thepoints 74 75.

the rolls on n are suificient to eifectively work or treat the entiresurface of a hide or skin.

I have herein shown one form of carrier and mechanism for reciprocatingthe same; but I do not desire to limit my invention to the particularform of carrier and its operating mechanism herein shown. I have hereinshown the rolls or tools'm n 0 p mounted in levers; but I do not desireto limit my invention to this particular manner of supporting saidtools. ,The member 12 of the carrier is preferably made yielding, asshownin Figs. 4 to 6, inclusive, in which the said member is shown asfast on a rock-shaft 80, supported in the side frames. 13 of the carrierand provided at its opposite ends with cranks or arms 81, which have theupper ends projected over the side frames 13 and engaged by the springs15, which normally force the cranks 81 upward until arrested by asuitable stop,- shown as a nut 82 on the end of the screw or bolt 16.
